She also said that Brand, 38, was not comfortable with the singer being his equal.

"I think a lot of times strong men do want an equal, but then they get that equal and they're, like, I can't handle the equalness. He didn't like the atmosphere of me being the boss on tour".

"So that was really hurtful, and it was very controlling, which was upsetting. I felt a lot of responsibility for it ending, but then I found out the real truth, which I can't necessarily disclose", she added.
